Abstract

Provided is an adjustable nonlinear load configuration system which can be used for calibration test and performance verification of power grid equipment such as an uninterruptible power supply, a power conditioner and the like. The adjustable nonlinear load configuration system is characterized by comprising a power input part, a voltage and current measuring unit, a full-wave rectification part, an adjustable capacitor load part, an adjustable resistor load part, a control unit, and a user interface unit which are successively connected. The controller unit is connected with the program control switches of capacitors in the adjustable capacitor load part and the program control switches of resistors in the adjustable resistor load part via a controlled quantity output module, and is connected with a capacitive current measuring device and a resistive current measuring device in the voltage and current measuring unit, and an AC current measuring device and an AC voltage measuring device in the power input part. The adjustable capacitor load part is formed by multiple capacitors in parallel. The adjustable resistor load part is formed by multiple resistors in parallel.

Description

technical field [0001] The invention relates to a load configuration technology in power supply testing, in particular to an adjustable non-linear load configuration system. Background technique [0002] The calibration test and performance verification of power grid equipment such as uninterruptible power supply and purification power supply require load configuration. However, there is no similar product on the market, so the present invention can fill the gap in the current market. Contents of the invention [0003] Aiming at the defects or deficiencies in the prior art, the present invention provides an adjustable non-linear load configuration system, which provides a definite topology, adjustable power and power factor, adjustable phase number, and cascadable non-linear loads. In the test of power grid equipment such as uninterruptible power supply and purification power supply, it provides adjustable non-linear load conditions, which can be used for calibration testi...
